Last days I have read a lot of papers about different topics such as FOL, inference, artificial intelligence, large scale reasoning, rule engines, etc. I have collected all these references in ROCAS wiki<\/a>\u00a0with the objective of saving all relevant works that can help me to finally develop our semantic reasoner for large datasets.<\/p>\n

This afternoon I have found a paper entitled as “Making Web-Scale Semantic Reasoning More Service- Oriented: The Large Knowledge Collider<\/a>” that presents the whole architecture of the well-know project LarKc<\/a>, in some sense the ROCAS project was inspired by this European project but with a restricted scope and different objectives. This paper has two main points for me:<\/p>\n

    \n
  1. One of the authors is\u00a0Zhisheng Huang<\/a> who helped me in 2004 to use his Distributed Logic Programming system to animate humanoids when I was developing my final degree project to get the Bachelor Degree.<\/li>\n
  2. From a research point of view, authors present a compilation of works made during the execution of the LarKc project that should be relevant to ROCAS. It is not a research paper but a good summary of this project.<\/li>\n<\/ol>\n

    This is a short post but I want to highlight that the world is small enough to meet same people (in this case researchers) again and again! It is incredible! \ud83d\ude42<\/p>\n

    Finally, I would also like to report my first progresses in the development. I have deployed a job in Hadoop to perform the classical graph-algorithm “Breadth-First Search”, this is one of the tries I am thinking about for performing reasoning tasks…the other approches can be summarized:<\/p>\n

      \n
    1. Distribute Jena rule engine (reusing source code)<\/li>\n
    2. Develop from scratch the typical backward chain engine using unification and resolution<\/li>\n
    3. Mix of 1 and 2 to avoid parsing rules, matching triples, etc.<\/li>\n
    4. Build a graph (rules in backward chain can be shown as an AND\/OR tree) and try to infer new facts using unification and search.<\/li>\n
    5. …<\/li>\n<\/ol>\n
