Dataset Card for Armenian Address Extraction Dataset

This dataset consists of 2,271 records containing raw Armenian utility maintenance/planned outage announcement texts paired with structured address components extracted from them. The raw texts primarily originate from public announcements (such as those by the Electric Networks of Armenia) notifying the public of scheduled maintenance, and the dataset breaks down these notices into granular, queryable geographic attributes.

Dataset Details

Dataset Description

• Curated by: Elena Volkova
• Language(s) (NLP): Armenian (hy)
• License: Open Database License (ODbL) or Creative Commons Attribution 4.0 International (CC BY 4.0)

Dataset Sources

Parsed data from public websites ena.am and veolia.am

Uses

Direct Use

This dataset is intended for training, fine-tuning, and evaluating machine learning models on tasks such as:

1. Named Entity Recognition (NER) and Slot Filling for Armenian address components.
2. Address Parsing (converting unstructured text addresses into structured JSON/CSV formats).
3. Information Extraction (IE) from official government or utility announcements in the Armenian language.

Out-of-Scope Use

• Parsing addresses in languages other than Armenian.
• Geocoding tasks (converting text to exact latitude/longitude coordinates) without external lookup databases, as coordinate details are not included in this dataset.
• Extracting postal codes/ZIP codes, as they are generally not present in this source material.

Dataset Structure

The dataset contains a single split of 2,271 rows sorted by the key column. Each record consists of the following 9 fields:

• key (Integer): Unique identifier / group key matching the announcement event.
• text (String): Raw Armenian announcement text detailing the maintenance schedule and affected locations.
• region (String): The target province/state/region (e.g., Երևան or Արարատի մարզ).
• cityname (String): The name of the city, town, or village.
• citytype (String): The settlement type class (e.g., քաղաք for city, գյուղ for village).
• district (String): The administrative district or neighborhood (e.g., Կենտրոն, Շենգավիթ).
• street (String): The street name (e.g., Չարենցի փողոց).
• bldnum (String): The specific building number.
• bldlist (String): A list, range, or collection of affected building numbers (e.g., 23-31, 41-55, 87-103).

If there are several addresses in the 'text'-field, then there will be several strings for this text in the dataset with one structured address in each string. In the jsonl-file this strings are united to the one with 'text' and list of all structured addresses corresponding to the text.

Dataset Creation

Curation Rationale

Public utility announcements in Armenia are frequently published as large blocks of unstructured text. This makes it difficult to query or filter alerts by a specific street, neighborhood, or building. Structuring this data helps build models that can automatically parse and categorize locations affected by service interruptions.

Source Data

• Source Data Type: Public utility maintenance and service outage announcements.
• Source Language: Armenian.

Data Collection and Processing

Data was gathered from official public utility notification feeds (such as the Electric Networks of Armenia - Հայաստանի էլեկտրական ցանցեր). Unstructured announcement texts were processed and segmented. Text cleanup included lowercasing and normalizing common Armenian address keywords (e.g. converting Մարզ to մարզ, Փողոց to փողոց, etc.) to maintain consistency across records.

Who are the source data producers?

The source data is produced by public utility companies and service providers operating in the Republic of Armenia.

Annotations [optional]

Annotation process

The address segments were annotated and structured using a dedicated local database curation and web interface tool. Annotators verified the extracted street names, building numbers, and districts to align them with standard Armenian geographic naming conventions (using references like OpenStreetMap databases).

Who are the annotators?

Elena Volkova (dataset developer/curator).

Personal and Sensitive Information

This dataset does not contain personal names, phone numbers, email addresses, or private individual records. It contains only public physical address structures and building designations that were published in open, public maintenance announcements.

Bias, Risks, and Limitations

• Domain Bias: Because the source texts are utility announcements, the wording, syntax, and address formats are highly specific to maintenance reports. Models trained on this dataset might not perform as well on general postal addresses, package shipping labels, or casual chat queries.
• Geographic Bias: The data is heavily concentrated around major urban administrative areas (such as Yerevan and its districts) and municipal centers. Rural areas may have less granular street-level representation due to how outage notices are clustered.

Recommendations

Users should be made aware of the risks, biases and limitations of the dataset. More information needed for further recommendations.
