<p class="p1">Keys consisting of variable-length chamcter strings from the front and rear of surnames, derived by analysis of author names in a particular data base, am used to provide approximate representations of author names. When combined in appropriate ratios, and used together with keys for each of the first two initials of personal names, they provide a high degree of discrimination in search.</p> <p class="p1">Methods for optimization of key-sets are described, and the performance of key-sets varying in size between <span class="s1">150 </span>and <span class="s1">300 </span>is determined at file sizes of up to <span class="s1">50,000 </span>name entries. The effects of varying the proportions of the queries present in the file are also examined. The results obtained with fixed-length keys are compared with those for variable-length keys, showing the latter to be greatly superior.</p> <p class="p1">Implications of the work for a variety of types of information systems are discussed.</p>

Innovation Model

In the past year, knowledge and innovation management have acquired increasing relevance in organizations. In the last decade, open innovation strategy, and in particular, crowdsourcing innovation model has also gained increasing importance. This model is seen as a new innovation model, capable of accelerating the innovation process. Therefore, it is important to understand how organizations can best take advantage of this innovation model. This paper approaches in two ways for commercializing intellectual property: crowdsourcing innovation, and intellectual property marketplaces. Thus, with the intention of understanding the concepts and practices, the study started by collecting scientific articles through bibliographic data bases. The paper provides knowledge about concepts and practices underlying the ways for commercializing intellectual property. It also contributes with a proposal of architecture for an intellectual property marketplace, based on the analysis of practices about crowdsourcing innovation and intellectual property marketplaces. This architecture is still in a draft stage, but already includes helpful insights for organizations interested in applying the open innovation strategy.

Homogeneous Data

<p class="p1">Conventional approaches to processing records of linguistic origin for storage and retrieval tend to regard the data as immutable. The data generally exhibit great variety and disparate frequency distributions, which are largely ignored and which entail either the storage of extensive lists of items or the use of complex numerical algorithms such as hash coding. The results in each case are far from ideal.</p> <p class="p1">The variety-generator approach seeks to reflect the microstructure of data elements in their description for storage and search, and takes advantage of the consistency of statistical characteristics of data elements in homogeneous data bases.</p> <p class="p1">In this paper, the application of the variety-generator approach to the description of personal author names from the INSPEC data base by means of small sets of keys is detailed. It is shown that high degrees of partitioning of names can be obtained by key-sets generated from the initial characters of surnames, fmm the terminal characters of surnames, and from the initials.</p> <p class="p1">The implications of the findings for computer-based bibliographical informationsystems are discussed.</p>
