“…BP-QL is another approach proposed in [14], [15] for querying process defined by BPEL only, it can retrieve the models containing the specific nodes and paths. In [16], WISE, a workflow search engine, was proposed to return the most specific workflow hierarchies containing matching keywords. But all of the above works only focus on graph structure, not on semantics.…”

As business process management technology matures, organisations accumulate hundreds, even thousands of models whose management poses real challenges. One of these challenges concerns model retrieval where support should be provided for the formulation and efficient evaluation of business process model queries. Recent years, queries based on behavioral information attracted more and more attentions both in the academic and industrial fields. However, there is not a widely accepted formal language to express the behavioral requirements. And the efficiency of the behavioral queries is another challenge when the process models contains arbitrary loop and/or extra-large parallel structures. The complete finite prefix (CFP) has been widely used to express the partial-order semantics of a Petri net. In this paper, we first extend CFP by connecting the cut-off events to continuation events, we call it temporal-order preserving complete finite prefix (TPCFP), where all the temporal relations between tasks can be extracted. Then we employ linear temporal logic formulae as the behavioral query language, whose formal semantics are defined over the TPCFP. The related algorithms are implemented in BeehiveZ 1 . Experimental results are investigated with real-life processes and artificial processes in detail.

“…There are many opportunities for supporting keyword search on other types of structured data, including data extracted from text documents (e.g. parse tree databases), data warehouses [51,56], spatial and multimedia databases [7,60], workflows [45], and probabilistic databases. Furthermore, techniques that enable users to seamlessly access vast collections of heterogeneous data sources are in great demand.…”

Empowering users to access databases using simple keywords can relieve the users from the steep learning curve of mastering a structured query language and understanding complex and possibly fast evolving data schemas. In this tutorial, we give an overview of the state-of-the-art techniques for supporting keyword search on structured and semi-structured data, including query result definition, ranking functions, result generation and top-k query processing, snippet generation, result clustering, query cleaning, performance optimization, and search quality evaluation. Various data models will be discussed, including relational data, XML data, graph-structured data, data streams, and workflows. We also discuss applications that are built upon keyword search, such as keyword based database selection, query generation, and analytical processing. Finally we identify the challenges and opportunities of future research to advance the field.
