Large volumes of social media content demand tools to better manage the flow. NodeXL implements a social and semantic network analysis application for end users that require no programming skills. Using the framework of a familiar spreadsheet, NodeXL allows users to extract collections of connections among social media users who are linked through patterns of reply, mention, or following relati...

In this paper, a single notion of exhaustivity will be defined in terms of relevance that accounts for (i) standard exhaustification; (ii) scalar readings; and the intuition that mention-some answers can sometimes be completely resolving. It will be shown that this notion of exhaustivity leaves something to be done for ‘only’. Moreover, an analysis will be given of ‘only’ in terms of relevance ...

Dr. Green: Yes, I would definitely agree with that. There are 2 factors: one is the type of operation and the other is the patient undergoing that operation. In terms of the patient, we have to consider a whole range of risk factors. For example, it is very important that surgeons obtain an adequate history from the patient, especially a history of previous VTE. A patient might neglect to menti...

The paper presents a method for estimating unknown user reviews in terms of which specific aspects of a particular item, such as a restaurant, a user would mention in a review that he/she would write about the item and also which sentiments the user would express about these aspects. Unlike the traditional rating-based recommendation methods, the proposed approach estimates user experiences of ...

Adverse drug reactions (ADRs) are one of the leading causes of mortality in health care. Current ADR surveillance systems are often associated with a substantial time lag before such events are officially published. On the other hand, online social media such as Twitter contain information about ADR events in real-time, much before any official reporting. Current state-of-the-art methods in ADR...

Disambiguating named entities in naturallanguage text maps mentions of ambiguous names onto canonical entities like people or places, registered in a knowledge base such as DBpedia or YAGO. This paper presents a robust method for collective disambiguation, by harnessing context from knowledge bases and using a new form of coherence graph. It unifies prior approaches into a comprehensive framewo...

is an information-theoretic measure of the dissimilarity between q = q 1, • • · ,qn and p = p 11 • • • , pn (H is also called cross-entropy, discrimination information, directed divergence, !-divergence, K-L number, among other terms). Various properties of relative entropy have led to its widespread use in information theory. These properties suggest that relative entropy has a role to play in...

We introduce a minimal language combining higher-order computation and linear algebra. This language extends the λ-calculus with the possibility to make arbitrary linear combinations of terms α.t+ β.u. We describe how to “execute” this language in terms of a few rewrite rules, and justify them through the two fundamental requirements that the language be a language of linear operators, and that...

The interpretation generated from a sentence of the form P and Q can often be different to that generated by Q and P, despite the fact that and has a symmetric truth-conditional meaning. We experimentally investigated to what extent this difference in meaning is due to the connective and and to what extent it is due to order of mention of the events in the sentence. In three experiments, we col...
