ISR - 9 August , 1965 XVIII - 1 XVIII . A PROGRAM TO EVALUATE THE ITERATIVE SEARCH PROCESS ( MORVAL )

چکیده
The various processing methods available in the Si v LART system can be studied singly or in combination 0 The use of combined processing methods can produce more accurate retrieval when the methods that are combined complement each other, producing different relevant documents near the top of the rank list. To aid in the evaluation of multiple processing methods, a program named MORVAL has been written which runs as a post-processor of SMART retrieval operations. This program is used to merge the output from different computer runs of the main SMART system, and to compute evaluation measures for the merged output. MORVAL requires as input the document rank lists produced by each method for each request, and a set of Instructions telling which methods are to be merged in this run. For each request and each set of merged methods, a table is produced containing the rank list of the "top" 15' documents produced by the merged method, as well as the ranks of the relevant documents for the 2 merged method, and the SMART evaluation measures for the method. At the end of a MORVAL run, "Cleverdon-type" recall-precision graphs are prepared for each method (averaged over the requests in the run). Also, the averages of the evaluation measures over the requests are printed. The document rank list for a merged method is prepared by interleaving the rank lists for the individual methods which make up this merged method.

Matrilysin cleavage of corneal collagen type XVIII NC1 domain and generation of a 28-kDa fragment.
PURPOSE To localize endostatin and collagen type XVIII in human corneas and to characterize the enzymatic action of matrix metalloproteinases (MMPs) in the cleavage of collagen type XVIII and generation of endostatin in the cornea. METHODS Anti-endostatin and anti-hinge antibodies were generated using peptide fragments corresponding to the endostatin region and the adjacent nonendostatin hing...
متن کاملGuidelines for the use of meta-heuristics in combinatorial optimization
The 18th EURO Summer/Winter Institute (ESWI XVIII) took place during the spring 2000 in Switzerland. The topic of ESWI XVIII, ‘‘Meta-heuristics in Combinatorial Optimization’’, was selected due to its great current scientific interest: indeed, in recent years, several meta-heuristics have proved to be highly efficient for the solution of difficult combinatorial optimization problems. The Instit...
متن کاملSpecific collagen XVIII isoforms promote adipose tissue accrual via mechanisms determining adipocyte number and affect fat deposition.
Collagen XVIII is an evolutionary conserved ubiquitously expressed basement membrane proteoglycan produced in three isoforms via two promoters (P). Here, we assess the function of the N-terminal, domain of unknown function/frizzled-like sequences unique to medium/long collagen XVIII by creating P-specific null mice. P2-null mice, which only produce short collagen XVIII, developed reduced bulk-a...

In this thesis study, the primary structure of the human α1(XVIII) polypeptide was elucidated, its tissue distribution was studied, and the phenotypic changes in the mouse eye due to lack of type XVIII collagen in a knock-out mouse model were studied further. In addition, the consequences of simultaneous lack of both type XVIII and XV collagen were studied in a mouse model lacking both of these...
