The Social Network Analysis approach (SNA), also known as sociometrics or actor-network analysis, investigates social structure on the basis of empirically recorded social ties between actors. It thereby aims to explain e.g. the processes of flow of information, spreading of innovations, or even pathogens throughout the network by actor roles and their relative positions in the network based on quantitative and qualitative analyses. While the approach has a strong mathematical and statistical component, the identification of pertinent social ties also requires a strong ethnographic background. With regard to social categorization, SNA is well suited as a bootstrapping technique for highly dynamic communities and under-documented contexts. Currently, SNA is widely applied in various academic fields. For sociolinguists, it offers a framework for explaining the patterning of linguistic variation and mechanisms of language change in a given speech community.
The social tie perspective developed around 1940, in the field of sociology and social anthropology based on the ideas of Simmel, and was applied later in fields such as innovation theory. In sociolinguistics, it is strongly connected to the seminal work of Lesley and James Milroy and their Belfast studies (1978, 1985). These authors demonstrate that synchronic speaker variation is not only governed by broad societal categories but is also a function of communicative interaction between speakers. They argue that the high level of resistance against linguistic change in the studied community is a result of strong and multiplex ties between the actors. Their approach has been followed by various authors, including Gal, Lippi-Green, and Labov, and discussed for a variety of settings; most of them, however, are located in the Western world.
The methodological advantages could make SNA the preferred framework for variation studies in Africa due to the prevailing dynamic multilingual conditions, often on the backdrop of less standardized languages. However, rather few studies using SNA as a framework have yet been conducted. This is possibly due to the quite demanding methodological requirements, the overall effort, and the often highly complex linguistic backgrounds. A further potential obstacle is the pace of theoretical development in SNA. Since its introduction to sociolinguistics, various new measures and statistical techniques have been developed by the fast growing SNA community. Receiving this vast amount of recent literature and testing new concepts is likewise a challenge for the application of SNA in sociolinguistics.
Nevertheless, the overall methodological effort of SNA has been much reduced by the advancements in recording technology, data processing, and the introduction of SNA software (UCINET) and packages for network statistics in R (‘sna’). In the field of African sociolinguistics, a more recent version of SNA has been implemented in a study on contact-induced variation and change in Pana and Samo, two speech communities in the Northwest of Burkina Faso. Moreover, further enhanced applications are on the way for Senegal and Cameroon, and even more applications in the field of African languages are to be expected.
The study of sociolinguistics constitutes a vast and complex topic that has yielded an extensive and multifaceted body of scholarship. Language is fundamentally at work in how we operate as individuals, as members of various communities, and within cultures and societies. As speakers, we learn not only the structure of a given language; we also learn cultural and social norms about how to use language and what content to communicate. We use language to navigate expectations, to engage in interpersonal interaction, and to go along with or to speak out against social structures and systems.
Sociolinguistics aims to study the effects of language use within and upon societies and the reciprocal effects of social organization and social contexts on language use. In contemporary theoretical perspectives, sociolinguists view language and society as being mutually constitutive: each influences the other in ways that are inseparable and complex. Language is imbued with and carries social, cultural, and personal meaning. Through the use of linguistic markers, speakers symbolically define self and society. Simply put, language is not merely content; rather, it is something that we do, and it affects how we act and interact as social beings in the world.
Language is a social product with rich variation along individual, community, cultural, and societal lines. For this reason, context matters in sociolinguistic research. Social categories such as gender, race/ethnicity, social class, nationality, etc., are socially constructed, with considerable variation within and among categories. Attributes such as “female” or “upper class” do not have universal effects on linguistic behavior, and sociolinguists cannot assume that the most interesting linguistic differences will be between groups of speakers in any simple, binary fashion. Sociolinguistic research thus aims to explore social and linguistic diversity in order to better understand how we, as speakers, use language to inhabit and negotiate our many personal, cultural, and social identities and roles.
Speech acts are acts that can, but need not, be carried out by saying and meaning that one is doing so. Many view speech acts as the central units of communication, with phonological, morphological, syntactic, and semantic properties of an utterance serving as ways of identifying whether the speaker is making a promise, a prediction, a statement, or a threat. Some speech acts are momentous, since an appropriate authority can, for instance, declare war or sentence a defendant to prison, by saying that he or she is doing so. Speech acts are typically analyzed into two distinct components: a content dimension (corresponding to what is being said), and a force dimension (corresponding to how what is being said is being expressed). The grammatical mood of the sentence used in a speech act signals, but does not uniquely determine, the force of the speech act being performed. A special type of speech act is the performative, which makes explicit the force of the utterance. Although it has been famously claimed that performatives such as “I promise to be there on time” are neither true nor false, current scholarly consensus rejects this view. The study of so-called infelicities concerns the ways in which speech acts might either be defective (say by being insincere) or fail completely.
Recent theorizing about speech acts tends to fall either into conventionalist or intentionalist traditions: the former sees speech acts as analogous to moves in a game, with such acts being governed by rules of the form “doing A counts as doing B”; the latter eschews game-like rules and instead sees speech acts as governed by communicative intentions only. Debate also arises over the extent to which speakers can perform one speech act indirectly by performing another. Skeptics about the frequency of such events contend that many alleged indirect speech acts should be seen instead as expressions of attitudes. New developments in speech act theory also situate them in larger conversational frameworks, such as inquiries, debates, or deliberations made in the course of planning. In addition, recent scholarship has identified a type of oppression against under-represented groups as occurring through “silencing”: a speaker attempts to use a speech act to protect her autonomy, but the putative act fails due to her unjust milieu.

In their conversational interactions with speakers, listeners aim to understand what a speaker is saying, that is, they aim to arrive at the linguistic message, which is interwoven with social and other information, being conveyed by the input speech signal. Across the more than 60 years of speech perception research, a foundational issue has been to account for listeners’ ability to achieve stable linguistic percepts corresponding to the speaker’s intended message despite highly variable acoustic signals. Research has especially focused on acoustic variants attributable to the phonetic context in which a given phonological form occurs and on variants attributable to the particular speaker who produced the signal. These context- and speaker-dependent variants reveal the complex—albeit informationally rich—patterns that bombard listeners in their everyday interactions.
How do listeners deal with these variable acoustic patterns? Empirical studies that address this question provide clear evidence that perception is a malleable, dynamic, and active process. Findings show that listeners perceptually factor out, or compensate for, the variation due to context yet also use that same variation in deciding what a speaker has said. Similarly, listeners adjust, or normalize, for the variation introduced by speakers who differ in their anatomical and socio-indexical characteristics, yet listeners also use that socially structured variation to facilitate their linguistic judgments. Investigations of the time course of perception show that these perceptual accommodations occur rapidly, as the acoustic signal unfolds in real time. Thus, listeners closely attend to the phonetic details made available by different contexts and different speakers. The structured, lawful nature of this variation informs perception.
Speech perception changes over time not only in listeners’ moment-by-moment processing, but also across the life span of individuals as they acquire their native language(s), non-native languages, and new dialects and as they encounter other novel speech experiences. These listener-specific experiences contribute to individual differences in perceptual processing. However, even listeners from linguistically homogenous backgrounds differ in their attention to the various acoustic properties that simultaneously convey linguistically and socially meaningful information. The nature and source of listener-specific perceptual strategies serve as an important window on perceptual processing and on how that processing might contribute to sound change.
Theories of speech perception aim to explain how listeners interpret the input acoustic signal as linguistic forms. A theoretical account should specify the principles that underlie accurate, stable, flexible, and dynamic perception as achieved by different listeners in different contexts. Current theories differ in their conception of the nature of the information that listeners recover from the acoustic signal, with one fundamental distinction being whether the recovered information is gestural or auditory. Current approaches also differ in their conception of the nature of phonological representations in relation to speech perception, although there is increasing consensus that these representations are more detailed than the abstract, invariant representations of traditional formal phonology. Ongoing work in this area investigates how both abstract information and detailed acoustic information are stored and retrieved, and how best to integrate these types of information in a single theoretical model.

Ditransitive predicates select for two internal arguments, and hence minimally entail the participation of three entities in the event described by the verb. Canonical ditransitive verbs include give, show, and teach; in each case, the verb requires an agent (a giver, shower, or teacher, respectively), a theme (the thing given, shown, or taught), and a goal (the recipient, viewer, or student). The property of requiring two internal arguments makes ditransitive verbs syntactically unique. Selection in generative grammar is often modeled as syntactic sisterhood, so ditransitive verbs immediately raise the question of whether a verb may have two sisters, requiring a ternary-branching structure, or whether one of the two internal arguments is not in a sisterhood relation with the verb.
Another important property of English ditransitive constructions is the two syntactic structures associated with them. In the so-called “double object construction,” or DOC, the goal and theme both are simple NPs and appear following the verb in the order V-goal-theme. In the “dative construction,” the goal is a PP rather than an NP and follows the theme in the order V-theme-to goal. Many ditransitive verbs allow both structures (e.g., give John a book/give a book to John). Some verbs are restricted to appear only in one or the other (e.g. demonstrate a technique to the class/*demonstrate the class a technique; cost John $20/*cost $20 to John). For verbs which allow both structures, there can be slightly different interpretations available for each. Crosslinguistic results reveal that the underlying structural distinctions and their interpretive correlates are pervasive, even in the face of significant surface differences between languages. The detailed analysis of these questions has led to considerable progress in generative syntax. For example, the discovery of the hierarchical relationship between the first and second arguments of a ditransitive has been key in motivating the adoption of binary branching and the vP hypothesis. Many outstanding questions remain, however, and the syntactic encoding of ditransitivity continues to inform the development of grammatical theory.

The non–Pama-Nyugan, Tangkic languages were spoken until recently in the southern Gulf of Carpentaria, Australia. The most extensively documented are Lardil, Kayardild, and Yukulta. Their phonology is notable for its opaque, word-final deletion rules and extensive word-internal sandhi processes. The morphology contains complex relationships between sets of forms and sets of functions, due in part to major historical refunctionalizations, which have converted case markers into markers of tense and complementization and verbal suffixes into case markers. Syntactic constituency is often marked by inflectional concord, resulting frequently in affix stacking. Yukulta in particular possesses a rich set of inflection-marking possibilities for core arguments, including detransitivized configurations and an inverse system. These relate in interesting ways historically to argument marking in Lardil and Kayardild. Subordinate clauses are marked for tense across most constituents other than the subject, and such tense marking is also found in main clauses in Lardil and Kayardild, which have lost the agreement and tense-marking second-position clitic of Yukulta. Under specific conditions of co-reference between matrix and subordinate arguments, and under certain discourse conditions, clauses may be marked, on all or almost all words, by complementization markers, in addition to inflection for case and tense.
The concept of Africa requires reflection: what does it mean to study a social phenomenon “in Africa”? Technology use in Africa is complex and diverse, showing various degrees of access across the continent (and in the Diaspora, and digital social inequalities—which are part and parcel of the political economy of communication—shape digital engagement. The rise of mobile phones, in particular, has enabled the emergence of technologically mediated literacies, text-messaging among them. Text-messaging is defined not only by a particular mode of communication (typically written on mobile phones, visual, digital), but it also favors particular topics (intimate, relational, sociable, ludic) and ways of writing (short, non-standard texts that are creative as well as multilingual). The genre of text-messaging thus includes not only short message service (SMS) and (mobile) instant-messaging (which one might call prototypical one-to-one text messages), but also Twitter, an application that, like texting, favors brevity of expression and allows for one-to-many conversations. Access to Twitter is still limited for many Africans, but as ownership of smartphones is growing, so is Twitter use, and the African “Twittersphere” is emerging as an important pan-African space. At times, discussions are very local (as on Ghanaian Twitter), at other times regional (East African Twitter) or global (African Twitter and Black Twitter); all these are emic, folksonomic terms, assigned and discussed by users. Although former colonial languages, especially English, dominate in many prototypical text messages and on Twitter, the genre also provides important opportunities for writing in African languages. The choices made in the digital space echo the well-known debate between Chinua Achebe and Ngũgĩ wa Thiong’o: the Africanization of the former colonial languages versus writing in African languages. In addition, digital writers engage in multilingual writing, combining diverse languages in one text, and thus offer new ways of writing locally as well as shaping a digitally-mediated pan-African voice that draws on global strategies as well as local meaning.
Hearers and readers make inferences on the basis of what they hear or read. These inferences are partly determined by the linguistic form that the writer or speaker chooses to give to her utterance. The inferences can be about the state of the world that the speaker or writer wants the hearer or reader to conclude are pertinent, or they can be about the attitude of the speaker or writer vis-à-vis this state of affairs. The attention here goes to the inferences of the first type. Research in semantics and pragmatics has isolated a number of linguistic phenomena that make specific contributions to the process of inference. Broadly, entailments of asserted material, presuppositions (e.g., factive constructions), and invited inferences (especially scalar implicatures) can be distinguished.
While we make these inferences all the time, they have been studied piecemeal only in theoretical linguistics. When attempts are made to build natural language understanding systems, the need for a more systematic and wholesale approach to the problem is felt. Some of the approaches developed in Natural Language Processing are based on linguistic insights, whereas others use methods that do not require (full) semantic analysis.
In this article, I give an overview of the main linguistic issues and of a variety of computational approaches, especially those stimulated by the RTE challenges first proposed in 2004.
In the linguistic literature, the term theme has several interpretations, one of which relates to discourse analysis and two others to sentence structure. In a more general (or global) sense, one may speak about the theme or topic (or topics) of a text (or discourse), that is, to analyze relations going beyond the sentence boundary and try to identify some characteristic subject(s) for the text (discourse) as a whole. This analysis is mostly a matter of the domain of information retrieval and only partially takes into account linguistically based considerations. The main linguistically based usage of the term theme concerns relations within the sentence. Theme is understood to be one of the (syntactico-) semantic relations and is used as the label of one of the arguments of the verb; the whole network of these relations is called thematic relations or roles (or, in the terminology of Chomskyan generative theory, theta roles and theta grids). Alternatively, from the point of view of the communicative function of the language reflected in the information structure of the sentence, the theme (or topic) of a sentence is distinguished from the rest of it (rheme, or focus, as the case may be) and attention is paid to the semantic consequences of the dichotomy (especially in relation to presuppositions and negation) and its realization (morphological, syntactic, prosodic) in the surface shape of the sentence. In some approaches to morphosyntactic analysis the term theme is also used referring to the part of the word to which inflections are added, especially composed of the root and an added vowel.
