CFP
forWeb Content Analysis,
Semantics,

and Knowledge

We invite research contributions for the Web Content Analysis, Semantics, and Knowledge track at the 27th edition of The Web Conference (WWW 2018), to be held April 23-27, 2018 in Lyon, France (/www2018/).

The Web Content Analysis, Semantics, and Knowledge Track, welcomes submissions of original, high-quality papers related to the analysis of web data in all its forms, ranging from the content itself to the associated entities and related metadata. We also welcome the application of such analyses for knowledge generation and structuring, predictive analytics, topic discovery, pattern recognition, and other novel tasks. In previous years, ‘content analysis’ and ‘semantic and knowledge’ were in separate track. This year, we combined these tracks to emphasize the close relationship between these topics; the use of content to curate knowledge and the use of knowledge to guide content analysis and intelligent usage. Papers can focus on one or both topics.

Topics of interest include:

• Content analysis, clustering, summarisation, and classification
• Information extraction
• Data discovery and consolidation
• Multi-lingual and cross-lingual analysis and mining
• Event extraction, modeling, and monitoring
• Sentiment analysis and opinion mining
• Analysis of online reviews
• Analysis and measurements of Web evolution
• Information visualization as applied to Web data
• Content-based information diffusion
• Predictive analytics over Web and social media
• Detecting and tracking deceptions, fakes and disinformation
• Content recommendation
• Algorithms for large-scale content mining
• Gender and algorithmic bias in content analysis
• Bridging unstructured and structured data
• Statistical, semantic, and hybrid models for content analysis
• Semantic data extraction, linking, and integration
• Knowledge representation, querying, and reasoning
• Knowledge generation, ranking, validation, and representation
• Scalable techniques for creating large, web-based, structured, reusable, knowledge graphs
• Use of semantic annotations for improving search, browsing, personalization, and advertising.
• Semantics to enable intelligent or human-like behavior and human actions
• Semantic-driven web content curation
• Tools, datasets, and benchmarks, made available to researchers and practitioners
• Web content analysis for societal challenges (e.g., climate change, terrorism, aging, sustainability)
• Novel applications
