Examples

Example notebooks and scripts can be found in in the base repository under /examples. The examples directory is separated into /examples/kd and /examples/ir, with a complete case stufy of all the capabilities of MIKA under /examples/Case_Study_NTSB

Utils

The main components of utils are the Data class and dataset-specific functions, which are used throughout other examples. A dedicated Data example can be found under /examples/utils

• Data Example
  • Initiate object
  • Load file
    • Initiate loading information
    • Load the data
  • Prepare data
  • Preprocessing
  • Sentence Tokenization
  • Save results
  • Loading preprocessed data

IR

Information Retrieval examples can be found in /examples/IR, with two sub directories for corresponding publications.

• Search
  • Prepare Data: NTSB
  • Perform Search

KD

Knowledge Discovery examples can be found in /examples/KD, with sub directories for Hazard Extraction and Analysis of Trends (HEAT), Failure Modes and Effects Analysis (FMEA), and failure taxonomies. Within these subdirectories, there are separate directories that correspond to specific publications.
