Running Experiments on the AQL

The data in the Archive Query Log is highly sensitive (still, you can re-crawl everything from the Wayback Machine). For that reason, we ensure that custom experiments or analyses can not leak sensitive data (please get in touch if you have questions) by using TIRA as a platform for custom analyses/experiments. In TIRA, you submit a Docker image that implements your experiment. Your software is then executed in sandboxed mode (without internet connection) to ensure that your software does not leak sensitive information. After your software execution finished, administrators will review your submission and unblind it so that you can access the outputs.
Please refer to our dedicated TIRA tutorial as starting point for your experiments.

Crawling

For running the CLI and crawl a query log on your own machine, please refer to the instructions for single-machine deployments. If instead you want to scale up and run the crawling pipelines on a cluster, please refer to the instructions for cluster deployments.

Single-Machine (PyPi/Docker)

To run the Archive Query Log CLI on your machine, you can either use our PyPi package or the Docker image. (If you absolutely need to, you can also install the Python CLI or the Docker image from source.)

Installation (PyPi)

First you need to install Python 3.10 and pipx (this allows you to install the AQL CLI in a virtual environment). Then, you can install the Archive Query Log CLI by running:

pipx install archive-query-log

Now you can run the Archive Query Log CLI by running:

aql --help

Installation (Python from source)

First install Python 3.10, and clone this repository. From inside the repository directory, create a virtual environment and activate it:

python3.10 -m venv venv/
source venv/bin/activate

Install the Archive Query Log by running:

pip install -e .

Now you can run the Archive Query Log CLI by running:

aql --help

Installation (Docker)

You only need to install Docker.

Note: The commands below use the syntax of the PyPi installation. To run the same commands with the Docker installation, replace aql with docker run -it -v "$(pwd)"/config.override.yml:/workspace/config.override.yml ghcr.io/webis-de/archive-query-log, for example:

docker run -it -v "$(pwd)"/config.override.yml:/workspace/config.override.yml ghcr.io/webis-de/archive-query-log --help

Installation (Docker from source)

First install Docker, and clone this repository. From inside the repository directory, build the Docker image like this:

docker build -t aql .

Note: The commands below use the syntax of the PyPi installation. To run the same commands with the Docker installation, replace aql with docker run -it -v "$(pwd)"/config.override.yml:/workspace/config.override.yml aql, for example:

docker run -it -v "$(pwd)"/config.override.yml:/workspace/config.override.yml aql --help

Configuration

Crawling the Archive Query Log requires access to an Elasticsearch cluster and some S3 block storage. To configure access to the Elasticsearch cluster and S3, add a config.override.yml file in the current directory, with the following contents. Replace the placeholders with your actual credentials:

es:
  host: "<HOST>"
  port: 9200
  username: "<USERNAME>"
  password: "<PASSWORD>"
s3:
   endpoint_url: "<URL>"
   bucket_name: archive-query-log
   access_key: "<KEY>"
   secret_key: "<KEY>"

Toy Example: Crawl ChatNoir SERPs from the Wayback Machine

The crawling pipeline of the Archive Query Log can best be understood by looking at a small toy example. Here, we want to crawl and parse SERPs of the ChatNoir search engine from the Wayback Machine.

Add an archive service

Add new web archive services (e.g., the Wayback Machine) to the AQL by running:

aql archives add

We maintain a list of compatible web archives below.

Compatible archives

The web archives below are known to be compatible with the Archive Query Log crawler and can be used to mine SERPs.

Name	CDX API URL	Memento API URL
Wayback Machine	https://web.archive.org/cdx/search/cdx	https://web.archive.org/web/

Add a search provider

Add new search providers (e.g., Google) to the AQL by running:

aql providers add

A search provider can be any website that offers some kind of search functionality. Ideally, you should also look at common prefixes of the URLs of the search results pages (e.g., /search for Google). Narrowing down URL prefixes helps to not crawl too many captures that do not contain search results.

Refer to the import instructions below to import providers from the AQL-22 YAML file format.

Build source pairs

Once you have added at least one archive and one search provider, we want to crawl archived captures of SERPs for each search provider and for each archive service, that is, we compute the cross product of archives and the search providers' domains and URL prefixes (roughly: archive×provider). Start building source pairs (i.e., archive–provider pairs) by running:

aql sources build

Running the command again after adding more archives or providers automatically creates the missing source pairs.

Fetch captures

For each source pair, we now fetch captures from the archive service, that correspond to the provider's domain and URL prefix given in the source pair.

aql captures fetch

Again, running the command again after adding more source pairs automatically fetches the missing captures.

Parse URLs

Not every capture necessarily points to a search engine result page (SERP). But usually, SERPs contain the user query in the URL, so we can filter out non-SERP captures by parsing the URLs.

aql serps parse url-query

Parsing the query from the capture URL will add SERPs to a new, more focused index that only contains SERPs. From the SERPs, we can also parse the page number and offset of the SERP, if available.

aql serps parse url-page
aql serps parse url-offset

All the above commands can be run in parallel, and they can be run multiple times to update the SERP index. Already parsed SERPs will be skipped.

Download WARCs

Up to this point, we have only fetched the metadata of the captures, most prominently the URL. However, the snippets of the SERPs are not contained in the metadata, but only on the web page. So we need to download the actual web pages from the archive service.

aql serps download warc

This command will download the contents of each SERP to a WARC file that is stored in the configured S3 bucket. A pointer to the WARC file is stored in the SERP index so that we can quickly access a specific SERPs contents later.

Parsing WARCs

Import from AQL-22

We support automatically importing providers and parsers from the AQL-22 YAML-file format (see data/selected-services.yaml). To import the services and parsers from the AQL-22 YAML file, run:

aql providers import
aql parsers url-query import
aql parsers url-page import
aql parsers url-offset import

We also support importing a previous crawl of captures from the AQL-22 file system backend:

aql captures import aql-22

Cluster (Helm/Kubernetes)

Running the Archive Query Log on a cluster is recommended for large-scale crawls. We provide a Helm chart that automatically starts crawling and parsing jobs for you and stores the results in an Elasticsearch cluster.

Installation

Just install Helm and configure kubectl for your cluster.

Configuration

Crawling the Archive Query Log requires access to an Elasticsearch cluster and some S3 block storage. Configure the Elasticsearch and S3 credentials in a values.override.yaml file like this:

elasticsearch:
  host: "<HOST>"
  port: 9200
  username: "<USERNAME>"
  password: "<PASSWORD>"
s3:
  endpoint_url: "<URL>"
  bucket_name: archive-query-log
  access_key: "<KEY>"
  secret_key: "<KEY>"

Deployment

Let's deploy the Helm chart on the cluster (we're testing first with --dry-run to see if everything works):

helm upgrade --install --values helm/archive-query-log/values.override.yaml --dry-run archive-query-log helm/archive-query-log

If everything worked and the output looks good, you can remove the --dry-run flag to actually deploy the chart.

Uninstall

If you no longer need the chart, you can uninstall it:

helm uninstall archive-query-log

}

Development

Refer to the local Python installation instructions to set up the development environment and install the dependencies.

Then, also install the test dependencies:

pip install -e .[tests]

After having implemented a new feature, you should the check code format, inspect common LINT errors, and run all unit tests with the following commands:

flake8 archive_query_log  # Code format
pylint archive_query_log  # LINT errors
mypy archive_query_log    # Static typing
bandit -c pyproject.toml -r archive_query_log  # Security
pytest archive_query_log  # Unit tests

Add new tests for parsers

At the moment, our workflow for adding new tests for parsers goes like this:

1. Select the number of tests to run per service and the number of services.
2. Auto-generate unit tests and download WARCs with generate_tests.py
3. Run the tests.
4. Failing tests will open a diff editor with the approval and a web browser tab with the Wayback URL.
5. Use the web browser dev tools to find the query input field and search result CSS paths.
6. Close diffs and tabs and re-run tests.

Abstract

The Archive Query Log (AQL) is a previously unused, comprehensive query log collected at the Internet Archive over the last 25 years. Its first version includes 356 million queries, 166 million search result pages, and 1.7 billion search results across 550 search providers. Although many query logs have been studied in the literature, the search providers that own them generally do not publish their logs to protect user privacy and vital business data. Of the few query logs publicly available, none combines size, scope, and diversity. The AQL is the first to do so, enabling research on new retrieval models and (diachronic) search engine analyses. Provided in a privacy-preserving manner, it promotes open research as well as more transparency and accountability in the search industry.
