## Introduction

OpenLA is an open-source library for e-book log analysis.

This Python library helps reduce redundant development when preprocessing e-book logs:
calculating reading times for each learner, counting up operations, page-wise summary of student behavior, etc.

![OpenLA concept](https://github.com/limu-research/openla/raw/main/source/images/OpenLA_concept.jpg?openla=2022-04-12)

## API concept

Four preprocessing processes are essential and common in e-book log analysis: getting course information, converting the log into a form suitable for analysis, extracting the required information, and visualizing the data.

In order to improve efficiency and reduce reiteration in these processes, OpenLA provides the corresponding four modules: Course Information, Data Conversion, Data Extraction, and Data Visualization.

## Installation

OpenLA is [available on PyPi](https://pypi.org/project/OpenLA/). You can install it with `pip`.

```sh
pip install OpenLA
```

## Datasets for OpenLA

The dataset used in this library has the same structure as the open source ones used to conduct [Data Challenge Workshops in LAK19 and LAK20](https://sites.google.com/view/lak20datachallenge).

We target [BookRoll](https://www.let.media.kyoto-u.ac.jp/en/project/digital-teaching-material-delivery-system-bookroll/) logs, but logs from other systems can be adapted.

The dataset may include up to four types of files.

### Course\_#\_EventStream.csv

- Data of the logged activity data from learners' interactions with the BookRoll system
- Columns: `userid`, `contentsid`, `operationname`, `pageno`, `marker`, `memo_length`, `devicecode`, and `eventtime`

### Course\_#\_LectureMaterial.csv

- Information about the length of the lecture materials used
- Columns: `lecture`, `contentsid`, and `pages`

### Course\_#\_LectureTIme.csv

- Information about the schedule of the lectures
- Columns: `lecture`, `starttime`, and `endtime`

### Course\_#\_QuizScore.csv

- Data on the final score for each student
- Columns: `userid` and `score`

Note: from version 0.2.1, OpenLA can treat grading data, which was not present in the LAK19 and LAK20 datasets.

### Course\_#\_GradePoint.csv

- Data on the final grade for each student
- Columns: `userid` and `grade`

Where `#` is the course id. BookRoll is an e-book system to record learning activities.

If you need a sample dataset, please contact openla@limu.ait.kyushu-u.ac.jp .
