Social Web analysis and Web mining, which includes effective methods for the analysis of Social Web content, analysis of community structures, discovery of evidence for content appraisal, analysis of trust and provenance, and scalability of analysis methods.

Event detection and consolidation, which includes informa-tion extraction technologies for detection of events and for detecting entities related to events; methods for con-solidating event, entity and topic information within and between archives, models for events, covering different levels of granularity, and their relations.

Perspective, Opinion and Sentiment detection, which includes scalable methods for detecting and analysing opinions, perspectives taken, and sentiments expressed in the Web and especially Social Web content.

Concise content purging, which includes detection of duplicates and near-duplicates and an adequate re- flection of content diversity with respect to textual content, images, and opinions.

Intelligent adaptive decision support, which includes methods for combining and reasoning about input from

social Web analysis, diversity and coverage aspects, extracted information, domain knowledge and

heuristics, etc.; methods for adapting the decision strategies to inputs received.

Advanced Web Crawling, which includes the integration of event-centred and entity-centred strate-gies, the use of social Web clues in crawling decisions and methods for translating by example and descriptive crawling specifications into crawling strategies.

Approaches for “semantic preser-vation”, which includes methods for enabling longterm interpretability of the archive content; methods for preserving the original context of perception and discourse in a semantic way; methods for deal-ing with evolution on the semantic layer.

ARCOMEM’s aim is to help transform archives into collective memories that are more tightly integrated with their community of users and exploit Social Web and the wisdom of crowds to make Web archiving a more selective and meaning-based process.

In order to reach its ambitious scien-tific and technological objectives, advanced research is required in the ARCOMEM project. This includes research in the following areas >>>>>
