despite a highly beneficial role of water soluble arabinoxylans, the information about the effect of their addition on the properties of rye dough is lacking. the aim of this study was to check the influence of their modification methods and properties on water binding capacity of rye flour and suggest some possible explanations for the action of various fractions of arabinoxylans. three modifi...
BACKGROUND Linking cancer registry and administrative data can reveal health care use patterns among cancer patients. The Canadian Cancer Registry (CCR) contains personal health insurance numbers (HINs) that facilitate linkage to hospitalization information in the Discharge Abstract Database (DAD). DATA AND METHODS Valid HINs, captured in the CCR or obtained through probabilistic linkages to ...
The problem of record linkage is often seen simply in terms of making links between data points that might be generated from the same source. However, in many cases the grounds for linking items is itself not certain. In fact it is often desirable to learn, in an unsupervised manner, what form linked objects take in different databases. One simple case of this is the “one to many” linkage probl...
Many data sets contain temporal records over a long period of time; each record is associated with a time stamp and describes some aspects of a realworld entity at that particular time. From such data, users often wish to search for entities in a particular period and understand the history of one entity or all entities in the data set. A major challenge for enabling such search and exploration...
Probabilistic data linkage is an attractive data collection option when direct measurement is impossible or extremely costly. Furthermore, the cost of linking is typically small compared to the benefit that can be derived from analysis of the linked data. One important linkage application is where different data sets relating to the same individuals at different points in time are linked to pro...
As multimodal data becomes easier to record and store the question arises as to what practical use can be made of archived corpora, and in particular what tools allowing efficient access to it can be built. We use the AMI Meeting Corpus as a case study to build an automatic content linking device, i.e. a system for real-time data retrieval. The corpus provides not only the data repository, but ...
Deduplicating one data set or linking several data sets are increasingly important tasks in the data preparation steps of many data mining projects. The aim of such linkages is to match all records relating to the same entity. Research interest in this area has increased in recent years, with techniques originating from statistics, machine learning, information retrieval, and database research ...
Deduplicating one data set or linking several data sets are increasingly important tasks in the data preparation steps of many data mining projects. The aim is to match all records relating to the same entity. Research interest in this area has increased in recent years, with techniques originating from statistics, machine learning, information retrieval, and database research being combined an...
Research utilising the available mass databases of real world road crashes compiled by Police, government and insurers in Victoria provides much useful information for injury prevention research purposes. The record linkage of these datasets and hospital injury records has the potential to maximise the use of available data by researchers to extend the understanding of the causes, outcomes and ...
The task of linking multiple databases with the aim to identify records that refer to the same entity is occurring increasingly in many application areas. If unique identifiers for the entities are not available in all the databases to be linked, techniques that calculate approximate similarities between records must be used for the identification of matching pairs of records. Often, the record...
