Mental State Recognition and Communicative Effects
No full textSpeech acts in natural language dialogues can be regarded as intentional acts performed by a dialogue participant to influence the relevant aspects of the mental state of a recipient. In this paper, a framework is discussed for deriving the beliefs and intentions of a speaker from a certain speech act. To this end, the notion of a speech act is replaced by the formal notion of a communicative act. A communicative act is expressed in terms of prosodic and textual features of the utterance and connected by means of default rules to the conditions that must be fulfilled by a speaker in order to perform the act felicitously. To indicate preferences among sets of conditions, hierarchic default rules were introduced. The conditions are expressed in terms of beliefs and intentions of the speaker and the hearer and may be compared with Searle's felicity conditions on speech acts. It is argued, though, that some of the conditions can be derived from a formalization of general principles of rati..
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
