ALCIDE: co-occurrences and polarity of words

Our group is using the 3D library to graphically visualize co-occurrence networks within ALCIDE. The idea is to combine co-occurrences together with information about polarity of words involved in the network.

For Kennedy’s and Nixon’s speeches we have used SentiWords, a resource provided by FBK containing 155,000 words associated with a sentiment score.

Collaboration with ISIG

A key aspect of Digital Humanities is interdisciplinarity. In the past year, we have been collaborating with the colleagues of the Italian-German Historical Institute (ISIG) to build a digital infrastructure to analyze and navigate historical corpora. Projects like this can be tough.  Luckily we have ISIG-sponsored chocolate to face hard research times.

Temporal Content Annotation

Our group, in collaboration with ILC-CNR, TrentoRise and HLT-FBK, is organizing a task devoted to the EValuation of Events aNd Temporal Information in Italian text within the EVALITA 2014 organization campaign .

In addition to the main task on contemporary news stories, we propose a pilot task on temporal processing of historical texts to promote the application of NLP techniques to the Digital Humanities domain.

For this reason Rachele is annotating De Gasperi’s writings about the outbreak of World War 1 with our tool CAT (Content Annotation Tool) following the It-TimeML specifications.

Annotated texts will be used to evaluate the performances of automatic Temporal Processing tools.
