A study of the dirichlet priors for term frequency normalisation [PDF]

Proceedings of the 28th annual international ACM SIGIR conference on Research and development in information retrieval, 2005
In Information Retrieval (IR), the Dirichlet Priors have been applied to the smoothing technique of the language modeling approach. In this paper, we apply the Dirichlet Priors to the term frequency normalisation of the classical BM25 probabilistic model and the Divergence from Randomness PL2 model. The contributions of this paper are twofold.

Term Weighting Schemes for Slovak Text Document Clustering [PDF]

Journal of Electrical and Electronics Engineering, 2013
Text representation is the task of transforming the textual data into a multidimensional space with corresponding weights for every word. Wehave tested several widely used term weighting methods on manually created database from Slovak Wikipedia articles.

An improved soft frequency reuse scheme in long term evolution networks

上海师范大学学报. 自然科学版, 2017
In this paper,a modified soft frequency reuse(SFR) scheme is given to improve the performance of edge area and to mitigate the shortcomings of traditional SFR such as low business agility which is unable to adapt to dynamic spectrum allocation and ...

Correlation of term usage and term indexing frequencies

Information Processing & Management, 1988
There have been several studies on the distributions of index terms, title terms, authors and other elements used in searching bibliographic databases. What is needed is to relate this information of the actual usage of terms in searching. This study uses data from monitoring the actual usage of terms in an online catalog at the School of Library and ...

Short term synaptic depression imposes a frequency dependent filter on synaptic information transfer. [PDF]

PLoS Computational Biology, 2012
Depletion of synaptic neurotransmitter vesicles induces a form of short term depression in synapses throughout the nervous system. This plasticity affects how synapses filter presynaptic spike trains. The filtering properties of short term depression are

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Health‐Related Quality of Life and Symptom Severity Among Patients With PIK3CA‐Related Overgrowth Spectrum: A Mixed‐Methods Study to Understand Real‐World Experience With Alpelisib Treatment

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background PIK3CA‐related overgrowth spectrum (PROS) includes several rare overgrowth disorders resulting from somatic gain‐of‐function mutations in PIK3CA. Despite treatment advances, including the recent approval of alpelisib for PROS in the United States, literature detailing the patient experience with PROS is limited.
