A platform for collaborative semantic annotation
نویسندگان
چکیده
Data-driven approaches in computational semantics are not common because there are only few semantically annotated resources available. We are building a large corpus of public-domain English texts and annotate them semi-automatically with syntactic structures (derivations in Combinatory Categorial Grammar) and semantic representations (Discourse Representation Structures), including events, thematic roles, named entities, anaphora, scope, and rhetorical structure. We have created a wiki-like Web-based platform on which a crowd of expert annotators (i.e. linguists) can log in and adjust linguistic analyses in real time, at various levels of analysis, such as boundaries (tokens, sentences) and tags (part of speech, lexical categories). The demo will illustrate the different features of the platform, including navigation, visualization and editing.

Use of Semantic Similarity and Web Usage Mining to Alleviate the Drawbacks of User-Based Collaborative Filtering Recommender Systems
One of the most famous methods for recommendation is user-based Collaborative Filtering (CF). This system compares active user’s items rating with historical rating records of other users to find similar users and recommending items which seems interesting to these similar users and have not been rated by the active user. As a way of computing recommendations, the ultimate goal of the user-ba...

متن کاملTOPSAN: a dynamic web database for structural genomics
The Open Protein Structure Annotation Network (TOPSAN) is a web-based collaboration platform for exploring and annotating structures determined by structural genomics efforts. Characterization of those structures presents a challenge since the majority of the proteins themselves have not yet been characterized. Responding to this challenge, the TOPSAN platform facilitates collaborative annotati...
متن کاملThe design of a wiki-based curation system for the Ontology of Functions
Recently, studies [1] argued that statistical and linguistic methods can be applied to extract information from biomedical ontologies, and represent the identified relations in the top-level ontology Ontology of Functions (OF) [2]. However, human intervention is required in order to clear noise from the generated data. A simple platform for collaborative work is needed. We propose here the use ...
