This document discusses ranking query results in databases to return the most relevant results. It addresses two common problems: empty answers, when a query returns no results, and many answers, when a query returns too many results. For empty answers, it proposes automated ranking functions to return approximately matching tuples without revising the query. For many answers, it adapts probabilistic information retrieval models to rank tuples based on global and conditional scores of specified and unspecified attributes. The document also describes implementing a ranking system with pre-processing, intermediate storage, and a query processing component.

probabilistic ranking
The document proposes a probabilistic approach to ranking results of database queries when multiple tuples satisfy the query criteria. It calculates global and conditional scores for tuples based on attribute correlations learned from the query workload and data, and combines these into a ranking function. User studies on real estate and movie datasets show the conditional ranking approach outperforms a baseline that only considers global scores. The approach can be efficiently implemented using indexing and optimization techniques.
Query optimization to improve performance of the code execution
This document discusses query optimization techniques to improve the performance of code execution. It describes how object querying provides an abstraction for operations over collections of objects that allows the query evaluator to optimize queries dynamically at runtime. Specifically, it presents an example of using the Java Query Language (JQL) to perform an equi-join on two collections in a more succinct way compared to manually iterating over the collections, and discusses how the JQL query could be optimized using techniques like hash joins.
11.query optimization to improve performance of the code execution
1. The document discusses query optimization techniques to improve the performance of object querying in Java.
2. It presents the Java Query Language (JQL) which allows programmers to express queries over object collections in Java through a declarative syntax.
3. The key aspects of JQL implementation include a compiler that compiles JQL queries to Java code and a query evaluator that applies optimizations like hash joins and nested loops joins to efficiently evaluate the queries.
Distributed DBMS - Unit 2 - Overview of RDBMS
This document provides an overview of relational database concepts and normalization. It begins by defining a relational database as a collection of tables where each table represents a relation. An example database models employees and projects in a company. The document describes how normalization addresses issues like data repetition, insertion/deletion anomalies, and update anomalies. The goal of normalization is to break relations into smaller, independent tables through a multi-step process until reaching a normal form like 1NF, 2NF, 3NF or BCNF. Functional dependencies are key to the normalization process.
FINAL REVIEW
This document presents a traditional approach to predicting hard queries using a keyword analyzer over databases. It proposes using association analysis to find the top k results from search keywords. An algorithm is proposed to find the top k searched keyword items from a combination of keywords in a probabilistic method that predicts results quickly. The proposed system uses a keyword analyzer and frequent pattern tree generation to efficiently rank the top k results over a corrupted database.
Nose Dive into Apache Spark ML
This document discusses Apache Spark machine learning (ML) workflows for recommendation systems using collaborative filtering. It describes loading rating data from users on items into a DataFrame and splitting it into training and test sets. An ALS model is fit on the training data and used to make predictions on the test set. The root mean squared error is calculated to evaluate prediction accuracy.

Feature Extraction for Large-Scale Text Collections
Feature engineering is a fundamental but poorly documented component in LTR search applications.
As a result, there are still few open access software packages that allow researchers and practitioners to easily simulate a feature extraction pipeline and conduct experiments in a lab setting.
This talk introduces Fxt, an open-source framework to perform efficient and scalable feature extraction. Fxt may be integrated into complex, high-performance software applications to help solve a wide variety of text-based machine learning problems.
The talk details how we built and documented a reproducible feature extraction pipeline with LTR experiments using the ClueWeb09B collection.
This LTR dataset is publicly available.
We’ll also discuss some of the benefits (feature extraction efficiency, model interpretation) of having open access tooling in this area for researchers and practitioners alike.

Rated Ranking Evaluator (FOSDEM 2019)
Every team working on information retrieval software struggles with the task of evaluating how well their system performs in terms of search quality(currently and historically). Evaluating search quality is important both to understand and size the improvement or regression of your search application across the development cycles, and to communicate such progress to relevant stakeholders. In the industry, and especially in the open source community, the landscape is quite fragmented: such requirements are often achieved using ad-hoc partial solutions that each time require a considerable amount of development and customization effort. To provide a standard, unified and approachable technology, we developed the Rated Ranking Evaluator (RRE), an open source tool for evaluating and measuring the search quality of a given search infrastructure. RRE is modular, compatible with multiple search technologies and easy to extend.
Search Quality Evaluation to Help Reproducibility: An Open-source Approach
Every information retrieval practitioner ordinarily struggles with the task of evaluating how well a search engine is performing and to reproduce the performance achieved in a specific point in time.
Improving the correctness and effectiveness of a search system requires a set of tools which help measuring the direction where the system is going.
Additionally it is extremely important to track the evolution of the search system in time and to be able to reproduce and measure the same performance (through metrics of interest such as precison@k, recall, NDCG@k...).
The talk will describe the Rated Ranking Evaluator from a researcher and software engineer perspective.
RRE is an open source search quality evaluation tool, that can be used to produce a set of reports about the quality of a system, iteration after iteration and that could be integrated within a continuous integration infrastructure to monitor quality metrics after each release .
Focus of the talk will be to raise public awareness of the topic of search quality evaluation and reproducibility describing how RRE could help the industry.

Coling2014:Single Document Keyphrase Extraction Using Label Information
This document proposes two extensions to the TextRank algorithm to extract label-specific keyphrases from multi-labeled documents: 1) Personalized TextRank (PTR), which replaces PageRank with personalized page rank using label-specific features to bias the random walk; and 2) TextRank using Ranking on Data Manifolds with Sinks (TRDMS), which models the problem as a random walk over the document graph with sink and query nodes to penalize irrelevant terms. The approaches are evaluated on a subset of the multi-label EUR-Lex corpus and compared to manually extracted keyphrases, showing their effectiveness increases with the size of the evidence set used to identify label-specific features.

Analysis of the “KDD Cup-1999” Datasets
This document summarizes the "KDD Cup - 1999" data sets used for computer network intrusion detection. The data sets contain over 5 million connection records with 41 features each, representing different types of attacks including denial of service, user to root, remote to local, and probing attacks. The document discusses the data redundancy, imbalance, and partitioning of the data sets. It also provides sample code for analyzing the data sets in Python, Java, and R and concludes that while the data sets were useful for early intrusion detection research, they have limitations such as redundancy and imbalance that prompted the introduction of new data sets like NSL-KDD.
Analysis of the Datasets
The document analyzes several datasets using machine learning algorithms. It summarizes the KDD Cup 1999 and NSL-KDD intrusion detection datasets, describing their characteristics, experiments comparing different classifiers on the data, and issues with the original KDD Cup data. It also briefly outlines three other medical datasets examined - Hypothyroid, Chronic Kidney Disease, and a Leaf dataset.
Attribute Reduction:An Implementation of Heuristic Algorithm using Apache Spark
This document discusses an attribute reduction algorithm for weather forecast data using Apache Spark. It aims to reduce redundant attributes in weather forecast data to improve data mining algorithm performance and reduce costs. The algorithm uses rough set theory to build a weather forecast knowledge representation system. It proposes using Spark's in-memory computing benefits to implement an attribute reduction algorithm that uses a heuristic formula to reduce the search space and simplify the weather forecast decision table, improving computation power. The algorithm is tested on a small cluster to evaluate its ability to efficiently perform attribute reduction in parallel.
Optimized Access Strategies for a Distributed Database Design
Abstract Distributed Database Query Optimization has been an active area of research for Database research Community in this decade. Research work mostly involves mathematical programming and evolving new algorithm design techniques in order to minimize the combined cost of storing the database, processing transactions and communication amongst various sites of storage. The complete problem and most of its subsets as well are NP-Hard. Most of proposed solutions till date are based on use of Enumerative Techniques or using Heuristics. In this paper we have shown benefits of using innovative Genetic Algorithms (GA) for optimizing the sequence of sub-query operations over the enumerative methods and heuristics. A stochastic simulator has been designed and experimental results show encouraging improvements in decreasing the total cost of a query. An exhaustive enumerative method is also applied and solutions are compared with that of GA on various parameters of a Distributed Query, like up to 12 joins and 10 sites. Keywords: Distributed Query Optimization, Database Statistics, Query Execution Plan, Genetic Algorithms, Operation Allocation.
Dice.com Bay Area Search - Beyond Learning to Rank Talk
This talk describes how to implement conceptual search (semantic search) within a modern search engine using the word2vec algorithm to learn concepts. We also cover how to auto-tune the search engine parameters using black box optimization techniques, and the problems of feedback loops encountered when building machine learning systems that modify the user behavior used to train the system.
Top-K Dominating Queries on Incomplete Data with Priorities
This document discusses algorithms for finding the top-K dominating queries on incomplete datasets. It proposes using a skyline-based algorithm that incorporates priority values for each dimension. This allows the algorithm to determine dominance even when the values are missing for some dimensions. It works by bucketing the data based on bit representations, finding the local skylines within each bucket, and then calculating scores for objects based on their dominance over other objects while considering the priority of dimensions. The top-K objects with the highest scores are then returned as the results. This approach provides more accurate outputs for applications like movie recommendations by allowing users to specify dimension priorities.
Haystacks slides
his talk will feature some of my recent research into the alternative uses for Solr facets and facet metadata. I will develop the idea that facets can be used to discover similarities between items and attributes in a search index, and show some interesting applications of this idea. A common takeaway is that using facets and facet metadata in non-conventional ways enables the semantic context of a query to be automatically tuned. This has important implications for user-centric and semantically focused relevance.
A Study on Optimization of Top-k Queries in Relational Databases
This document discusses optimization of top-k queries in relational databases. It begins with an introduction to top-k queries and their increasing importance. It then discusses extending relational algebra and query optimization to integrate rank-join operators that can efficiently evaluate top-k queries. Specifically, it outlines enlarging the search space of plans to include those using rank-join operators, and providing a cost model for these operators to help the optimizer select the most efficient plan. The goal is to fully support efficient evaluation of top-k queries within relational database systems.

Search Quality Evaluation to Help Reproducibility : an Open Source Approach
Every information retrieval practitioner ordinarily struggles with the task of evaluating how well a search engine is performing and to reproduce the performance achieved in a specific point in time.
Improving the correctness and effectiveness of a search system requires a set of tools which help measuring the direction where the system is going.
Additionally it is extremely important to track the evolution of the search system in time and to be able to reproduce and measure the same performance (through metrics of interest such as precison@k, recall, NDCG@k...).
The talk will describe the Rated Ranking Evaluator from a researcher and software engineer perspective.
RRE is an open source search quality evaluation tool, that can be used to produce a set of reports about the quality of a system, iteration after iteration and that could be integrated within a continuous integration infrastructure to monitor quality metrics after each release .
Focus of the talk will be to raise public awareness of the topic of search quality evaluation and reproducibility describing how RRE could help the industry.
Enhancing Keyword Query Results Over Database for Improving User Satisfaction
Storing data in relational databases is widely increasing to support keyword queries but search results does not gives effective answers to keyword query and hence it is inflexible from user perspective. It would be helpful to recognize such type of queries which gives results with low ranking. Here we estimate prediction of query performance to find out effectiveness of a search performed in response to query and features of such hard queries is studied by taking into account contents of the database and result list. One relevant problem of database is the presence of missing data and it can be handled by imputation. Here an inTeractive Retrieving-Inferring data imputation method (TRIP) is used which achieves retrieving and inferring alternately to fill the missing attribute values in the database. So by considering both the prediction of hard queries and imputation over the database, we can get better keyword search results.

Haystack 2019 - Rated Ranking Evaluator: an Open Source Approach for Search Q...OpenSource Connections
Every team working on Information Retrieval software struggles with the task of evaluating how well their system performs in terms of search quality(at a specific point in time and historically).
Evaluating search quality is important both to understand and size the improvement or regression of your search application across the development cycles, and to communicate such progress to relevant stakeholders.
To satisfy these requirements an helpful tool must be:
- flexible and highly configurable for a technical user
- immediate, visual and concise for an optimal business utilization
In the industry, and especially in the open source community, the landscape is quite fragmented: such requirements are often achieved using ad-hoc partial solutions that each time require a considerable amount of development and customization effort.
To provide a standard, unified and approachable technology, we developed the Rated Ranking Evaluator (RRE), an open source tool for evaluating and measuring the search quality of a given search infrastructure. RRE is modular, compatible with multiple search technologies and easy to extend. It is composed by a core library and a set of modules and plugins that give it the flexibility to be integrated in automated evaluation processes and in continuous integrations flows.
This talk will introduce RRE, it will describe its latest developments and demonstrate how it can be integrated in a project to measure and assess the search quality of your search application.
The focus of the presentation will be on a live demo showing an example project with a set of initial relevancy issues that we will solve iteration after iteration: using RRE output feedbacks to gradually drive the improvement process until we reach an optimal balance between quality evaluation measures.Rated Ranking Evaluator: An Open Source Approach for Search Quality Evaluation

Query aware determinization of uncertain
This paper addresses the problem of determinizing probabilistic data to enable its use in legacy systems that only accept deterministic data. It proposes a query-aware approach that selects deterministic representations of probabilistic data to optimize the quality of answers to queries over that data. A key contribution is a branch-and-bound algorithm that finds an approximate near-optimal solution to the NP-hard problem of minimizing the expected cost of query answers. Empirical results demonstrate the algorithm is efficient and achieves high quality results close to the optimal.
Chapter15
The document discusses algorithms and techniques for query processing and optimization in relational database management systems. It covers translating SQL queries into relational algebra, algorithms for operations like selection, projection, join and sorting, using heuristics and cost estimates for optimization, and an overview of query optimization in Oracle databases.
Get started with R lang
R is an open source programming language used for data analysis and visualization. It allows users to process raw data into meaningful assets through packages that provide functions for tasks like data cleaning, modeling, and graphic creation. The document provides an introduction to R for beginners, including how to install R, basic commands and their uses, how to work with common data structures in R like vectors, matrices, data frames and lists, how to create user-defined functions, and how to import data into R.
Automated Essay Grading using Features Selection
This document describes research on developing an automated essay grading system using feature selection. The researchers extracted various features from essays, including bag-of-words, word and sentence counts, and structure. They used a sequential forward feature selection algorithm to identify the optimal subset of features that achieved the highest grading accuracy. This algorithm starts with an empty feature set and sequentially adds individual features, retaining features that improve the accuracy at each step. The goal is to develop a system that can grade essays consistently and reduce the labor required from human graders.
Implementation of query optimization for reducing run time
This document discusses query optimization techniques to improve performance. It proposes performing query optimization at compile-time using histograms of data statistics rather than at run-time. Histograms are used to estimate selectivity of query joins and predicates at compile-time, allowing a query plan to be constructed in advance and executed without run-time optimization. The technique uses a split and merge algorithm to incrementally maintain histograms as data changes. Selectivity estimation with histograms allows join and predicate ordering to be determined at compile-time for query plan generation. Experimental results showed this compile-time optimization approach improved runtime performance over traditional run-time optimization.
Parameter Estimation User Guide
This document provides guidance on using MATLAB to implement parameter estimation techniques such as output error and filter error methods. It describes using a "run object" in MATLAB to define the key components of a numerical simulation for parameter estimation of an aircraft constrained to 1 degree of freedom. The run object stores properties that specify the state and observation equations, number of states and parameters, and files needed to perform the simulation and parameter estimation. The document provides details on setting up and running the simulation, implementing the output error method for parameter estimation, and using continuation methods to analyze bifurcations of the system.
Oracle Sql Tuning
The document discusses tuning SQL queries in Oracle databases. It begins by noting that while tools can help, there is no single process for tuning every query as each case depends on factors like the schema design, data distribution and how the optimizer chooses a plan. The document then provides a methodology for investigating and tuning a query with poor performance, including getting the execution plan, checking it visually, and identifying possible causes like stale statistics, missing indexes or inefficient SQL.

It also discusses probabilistic and statistical approaches that use data statistics to determine query cutoffs. Finally, it summarizes work on minimizing expensive predicate evaluations through necessary probing.
probabilistic ranking
The document discusses probabilistic information retrieval and Bayesian networks for modeling document collections and queries. It introduces concepts like conditional probability, Bayes' theorem, and the probability ranking principle. It then describes the binary independence retrieval model and how Bayesian networks can model dependencies between document terms and concepts to improve upon the independence assumption. The use of Bayesian networks allows modeling both documents and queries as networks to estimate the probability that a document satisfies an information need.
probabilistic ranking
The document discusses integrating probabilistic functional networks to identify interactions relevant to specific biological processes. It introduces a method to score interactions based on their relevance to a process of interest using gene ontology annotations. The method is tested on Saccharomyces cerevisiae protein interaction data to build networks relevant to telomere maintenance and aging. Evaluation shows relevance networks contain more clustered genes of interest compared to networks built only on interaction confidence.
DB-IR-ranking
The document discusses the relationship between database systems and information retrieval (IR) systems. It notes that while they have traditionally operated in "parallel universes", addressing them together is now important for applications. It outlines some key differences and similarities between the two areas and discusses efforts to build more integrated database and IR platforms.
IR-ranking
The document proposes an automated approach for ranking tuples in the results of SQL queries over databases. It computes global and conditional scores for tuples based on attribute correlations learned from past query workloads and data statistics. At query time, it merges pre-computed ranked lists corresponding to the query attributes to efficiently retrieve the top-k results without a full table scan. Experiments on real datasets show the approach is efficient and provides high quality rankings preferred by users over alternative methods.
