What's a Part? On Formalizing Part-Whole Relations
نویسنده
چکیده
This paper deals with commonsense understanding of part-whole relations. A unifying definition for the different kinds of parts is proposed for one domain, that of rigid, man-made objects. First, the representation of objects via basic dimensions, reference systems and attributes is described. Then, different kinds of parts, based on the classification of Gerstl and Pribbenow (1996), are examined. Several problems with the seemingly uncomplicated notion of "part" are discussed. Modifying the representation of objects makes it possible to give one single definition of "a part P of an object O".

متن کاملA Note on the Compatibility of Part-Whole Relations with Foundational Ontologies
Parthood in mereology is one relation, and typically is included in foundational ontologies. Some of these foundational ontologies and many domain ontologies use a plethora of parthood and part-whole relations, such as ‘sub process’ and ‘portion’. This poses requirements on the foundational ontologies and, perhaps, Ontology, on what to do with these two different approaches to part-whole relati...
متن کاملModeling, Representing, and Configuring Restricted Part-Whole Relations
Part-whole relations are the backbone of configuration systems. In this paper, part-whole relations are combined with other relations and restrictions leading to here-called restricted aggregates. Depending on what is given, aggregates, parts, or/and relations between parts, different tasks have to be solved. General aggregation reasoning chunks are developed and represented with a configuratio...
متن کاملCommonsense in Parts: Mining Part-Whole Relations from the Web and Image Tags
Commonsense knowledge about part-whole relations (e.g., screen partOf notebook) is important for interpreting user input in web search and question answering, or for object detection in images. Prior work on knowledge base construction has compiled part-whole assertions, but with substantial limitations: i) semantically different kinds of part-whole relations are conflated into a single generic...
متن کاملA Method for Learning Part-Whole Relations
In this paper we describe a method for finding part-whole relations. The method consists of two steps: (i) finding phrase patterns for both explicit and implicit part-whole relations, and (ii) applying these patterns to find part-whole relation instances. We show results of applying this method to a domain of finding sources of carcinogens.
