How do words get their meanings? How can word meanings be represented and used by machines? We will explore three families of approaches to these questions from a computational perspective. Relational / structural methods such as semantic networks represent the meaning of words in terms of their relations to other words. Knowledge of the world through perception and action leads to the notion of external grounding, a process by which word meanings are 'attached' to the world. How an agent theorizes about, and conceptualizes its world provides yet another foundation for word meanings. We will examine each of these perspectives, and consider ways to integrate them.

This course explores topics related to the representation and expression of propositional attitudes (e.g. belief, knowledge, and desires) and speech acts (e.g. saying and asking) in natural language. The main focus will be on semantics of predicates such as believe, know, want, say, ask, etc. Other topics will include the syntax of main and embedded clauses and formal representation of the pragmatics of conversation. The course provides practice in written and oral communication.

I realize that "Modes of Assertion" is a rather cryptic title for the course. What we will explore are ways of modulating the force of an assertion. This will engage us in formal semantics and pragmatics, the theory of speech acts and performative utterances, and quite a bit of empirical work on a not-too-well understood complex of data.
"He obviously made a big mistake."
"It is obvious that he made a big mistake."
If you're like me you didn't feel much of a difference. But now see what happens when you embed the two sentences:
"We have to fire him, because he obviously made a big mistake."
"We have to fire him, because it is obvious that he made a big mistake."
One of the two examples is unremarkable, the other suggests that the reason he needs to be fired is not that he made a big mistake but the fact that it is obvious that he did.
We will try to understand what is going on here and look at related constructions not just in English but also German (with its famous discourse particles like ja) and Quechua and Tibetan (with their systems of evidentiality-marking, as recently studied in dissertations from Stanford and UCLA).

This course is concerned with Negative Polarity Items. While raising familiar foundational questions for linguistic theory, Negative Polarity Items enter into complex and often revealing interactions with a host of other phenomena in grammar. Investigating several such interactions, the course touches on topics such as focus, presupposition, exhaustification, quantification, (in)definiteness, modals and attitudes, comparison and superlatives, and questions.

This book is a comprehensive description of the grammar of Rapa Nui, the Polynesian language spoken on Easter Island. After an introductory chapter, the grammar deals with phonology, word classes, the noun phrase, possession, the verb phrase, verbal and nonverbal clauses, mood and negation, and clause combinations. The phonology of Rapa Nui reveals certain issues of typological interest, such as the existence of strict conditions on the phonological shape of words, word-final devoicing, and reduplication patterns motivated by metrical constraints. For Polynesian languages, the distinction between nouns and verbs in the lexicon has often been denied; in this grammar it is argued that this distinction is needed for Rapa Nui. Rapa Nui has sometimes been characterised as an ergative language; this grammar shows that it is unambiguously accusative. Subject and object marking depend on an interplay of syntactic, semantic and pragmatic factors. Other distinctive features of the language include the existence of a ‘neutral’ aspect marker, a serial verb construction, the emergence of copula verbs, a possessive-relative construction, and a tendency to maximise the use of the nominal domain. Rapa Nui’s relationship to the other Polynesian languages is a recurring theme in this grammar; the relationship to Tahitian (which has profoundly influenced Rapa Nui) especially deserves attention. The grammar is supplemented with a number of interlinear texts, two maps and a subject index.
