Abstract: A computer-implemented method of building a graph of organisation-specific knowledge includes the step of receiving conversation data. Words and phrases within the conversation data that describe organisational knowledge are detected. Sets of candidate knowledge tuples are extracted. Each tuple includes a sequence of elements that represent respective words, phrases, or sentences that describe an item of knowledge. The elements in each tuple are ordered according to an ontology of the item of knowledge. The tuples in each set describe respective versions of the item of organisational knowledge. Exemplar tuples that correspond to candidate tuples in respective sets that contain elements that occur more than a threshold number of times in the text are created. The graph is initialised from nodes representing the elements of the exemplar tuples. Edges represent relationships between the elements.

Abstract: A pipeline pig for removing scales and debris from the interior walls of a pipeline has a generally cylindrical central portion with a hollow core and a rounded end on each two ends of the cylindrical central portion, is produced of a flexible material to facilitate the movement of the pipeline pig through non-linear sections of a pipeline and buildups of scale and debris in a pipeline, has a solution which fills the hollow core, and includes a body which is formed as a peripheral fluid closed body composed of the flexible material.
