Information search is becoming increasingly demanding due to the booming of Consumer Generated Content (CGC) in online environment. This has led to growing scholarly interest in designing search features to accommodate diverse user preferences. Drawing on the Theory of Affordance Informativity, we advance ostensive informativity and performative informativity as focal mechanisms for search feat...

This paper proposes a characterization of useful thesaurus terms by the informativity of cooccurence with that term. Given a corpus of documents, informativity is formalized as the information gain of the weighted average term distribution of all documents containing that term. While the resulting algorithm for thesaurus generation is unsupervised, we find that high informativity terms correspo...

For a computational system to be intelligent, it should be able to perform, at least, basic deductions. Nonetheless, since deductions are, in some sense, equivalent to tautologies, it seems that they do not provide new information. The present article proposes a measure the degree of semantic informativity of valid deductions in a dynamic setting. Concepts of coherency and relevancy, displayed ...

In this paper we develop new data informativity based controller synthesis methods that extend existing frameworks in two relevant directions: a more general noise characterization terms of cross-covariance bounds and conditions for control on input-output data. Previous works have derived necessary sufficient noisy input-state with quadratic via an S-procedure. Although these do not capture ge...

Different languages present us with rather different likelihoods of deleting consonants. The very common deletion processes that target /t/ and /d/ in various English dialects have been discussed in detail in linguistic research, but English does not exhibit other well-known phonological processes such as /s/ deletion, a process that is very common in a number of Romance languages. A curious li...

How an object or event is described depends upon numerous factors that have been identified by prior research in linguistics, pragmatics, and psychology. What this prior research has not established, however, is what consequences the resulting choice of linguistic form has on subsequent comprehension processes. This dissertation begins with the assertion that the quantity of information encoded...

The assignment of phrasal prominence has been variously attributed to syntactic structure, part speech, predictability, informativity, and speaker's intent. A recent account asserts that is memorized on a by-word basis as Accent Ratio (AR), the likelihood word accented (Nenkova et al. 2007). We examined whether AR outperforms traditional predictors, in particular syntax if not, predictors shed ...
