Study Notes
Tolerant Retrieval in Information Retrieval
- Aims to match queries even with misspellings or variations, enhancing user search experience.
- Facilitates finding relevant results despite errors in user input.
Dictionary in Information Retrieval
- Each term requires two primary items to be stored:
- Term itself
- Associated posting list, indicating where the term appears in documents.
Data Structures for Dictionary Storage
- Main classes include:
- Hash tables
- Tries
- Search trees (e.g., AVL trees, B-trees)
- These structures enable efficient lookup, insertion, and deletion operations.
Advantages of Using Hash Tables
- Provide average-case constant time complexity for search operations.
- Efficiently handle large vocabularies and allow for quick access to terms.
Tolerant Search Engine Goals
- Designed to improve search effectiveness by accounting for user error.
- Enhances retrieval quality by broadening the scope of matching criteria.
Spelling Correction and Soundex
- Aim to correct input errors and phonetically match words to improve retrieval accuracy.
- Soundex allows phonetic searching, facilitating matches based on how words sound rather than exact spelling.
Project Management Aspects
- Day-to-day project management is typically handled by a project manager.
- The Project Executive oversees overall project strategy, resolving high-level policy issues.
Project Oversight and Policy Determination
- Overall policy, budget, and project scope are determined by the project sponsor or steering committee.
BPR Methodology Steps
- The first step in Business Process Reengineering (BPR) involves identifying and selecting processes for improvement.
- The second step includes analyzing and understanding existing processes to identify inefficiencies and opportunities for redesign.
